Update regressions for gasnet configurations
Update regressions for gasnet configurations

Remove timeout for optimizations/bulkcomm/alberto/Block/2dDRtoBDTest:
 - It has not timed out since last year when gasnet.fifo was running on the
   slower chap13. REGRESSIONS says it failed on 2015-01-26, but that was
   actually optimizations/bulkcomm/alberto/Block/2dBDtoDRTest. I can't imagine
   how those test names could have been confused :)

Remove timeout for studies/madness/aniruddha/madchap/test_likepy:
 - A .timeout file was re-added to quiet this test with
   daf2b2d450787e8b10156c39970e8213a6747018, it has not been noisy since then

Remove timeout for release/examples/benchmarks/ssca2/SSCA2_main:
 - This test only timed out for llvm.gasnet, not gasnet*. It was a one time
   event, and llvm.gasnet runs on one of the slower vms.

Move types/string/StringImpl/memLeaks/coforall from gasnet.fifo to gasnet*:
 - It can fail in any gasnet configuration, it's just much more frequent for
   gasnet.fifo. It took me a while to figure out the history of this test so I
   added more info in REGRESSIONS with a pointer to the email thread about it

Update some timeout dates:
 - Add date for studies/madness/aniruddha/madchap/test_gaxpy
 - Add end date to performance/ferguson/remote-tuple-write timeout range
 - Add date for studies/sudoku/dinan/sudoku
